Overloading concatenates (&) operator in VB.Net

Here, we will overload the concatenate (&) operator using the operator method to concatenate two string objects.

Program/Source Code:

The source code to overload concatenates the (&) operator is given below. The given program is compiled and executed successfully.

VB.Net code to overload concatenates (&) operator

'VB.net program to overload concatenate "&" operator.

Class Sample
    Dim X As String
    Sub SetX(ByVal val As String)
        X = val
    End Sub
    Public Shared Operator &(ByVal S1 As Sample, ByVal S2 As Sample) As String
        Dim temp As String
        temp = S1.X & S2.X
        Return temp
    End Operator
End Class

Module Module1
    Sub Main()
        Dim obj1 As New Sample()
        Dim obj2 As New Sample()
        Dim result As String

        obj1.SetX("Hello")
        obj2.SetX("World")

        result = obj1 & obj2

        Console.WriteLine("Result: {0}", result)
    End Sub
End Module

Output:

Result: HelloWorld
Press any key to continue . . .

Explanation:

In the above program, we created a class Sample that contains a method SetX() to set the value of data members. Here, we also implemented a method to overload the concatenates (&) operator to concatenate two strings.

After that, we created a module Module1 that contains the Main() method, the Main() method is the entry point for the program. And, we created two objects of Sample class and set the value of data member using SetX() method and then perform concatenate operation between objects and print the result on the console screen.
